Abstrakt: Soil salinity is a global issue that limits plant growth in agricultural fields and contributes to food crisis. Salt stressors impede plant's ionic, osmotic, and oxidative balance, as well as a variety of physiological functions. Exposure to salinity stress manifest considerable ROS clustering, entailing modification in performance of various organelles. To deal with salinity, plants use a variety of coping strategies, such as osmoregulation, ion-homeostasis, increased antioxidant synthesis, and so on. Nitric oxide (NO) is a pivotal signalling molecule that helps facilitate salt stress-induced physiological plant responses. A variety of evidences point to NO being produced under similar stress conditions and with similar kinetics as hydrogen peroxide (H 2 O 2 ). The interplay between H 2 O 2 and NO has important functional implications for modulating plant transduction processes. Besides, NO and calcium (Ca 2+ )-dependent pathways also have some connection in salt stress response mechanisms. Extensive crosstalk between NO and Ca 2+ signalling pathways is investigated, and it suggests that almost every type of Ca 2+ channel is under the tight control of NO, and NO acts as a Ca 2+ mobilising compound and aids in signal reliance. The review provides insights into understanding recent advances regarding NO's, Ca 2+ and H 2 O 2 role in salt stress reduction with entwine signaling mechanisms.
